RB-71D-4/4kw high-pressure fan

High pressure vortex fanQuanfeng Direct Sales Quanfeng Environmental Protection Technology Co., Ltd. is a modern enterprise specializing in the production and sales of air, gas, and fluid equipment, as well as environmental protection equipment (compression, vacuum). Through years of development, the company has formed a development pattern that mainly focuses on high-pressure fans, supplemented by other air and fluid equipment (vacuum pumps and blowers), integrating research and development, production, and sales, and aspires to become a leader in the domestic industry.

RB-71D-4/4kw high-pressure fanto configure:
1. Shell material: The high-pressure fan adopts * degree die cast aluminum, which is the same aluminum material as the Mercedes Benz wheel hub. Compared with ordinary aluminum alloy, die cast aluminum is stronger and has a more lightweight effect compared to iron shell fans.
2. Motor performance: The motor used in the high-voltage fan is a wideband, wide voltage motor, listed as single-phase 110V/230V industrial three-phase: 220/380/415/660V, etc. The motor frequency can be adjusted from 45-75HZ, with an IP55 protection level and F-class insulation level. Its advantages are beyond the reach of domestic motors and are highly favored by domestic and foreign customers.
3. Fan oil seal: The high-pressure fan adopts German MERKEL oil seal, and the German MERKEL material uses fluororubber that can withstand temperatures from -25 ℃ to 300 ℃. Compared to the general oil seal, its lip temperature is 20-50 ℃ higher than the working medium temperature during operation, making it more stable in performance, maintenance free, and has a longer lifespan.

RB-71D-4/4kw high-pressure fanApplication Introduction:

1. Textile equipment: vortex air pump, high-speed sock weaving machine; Coating thickness control and ensuring uniform thickness, removing moisture, drying, and yarn drawing machine.
2. Plastic auxiliary machine and central feeding system: In the use of the casting machine, in order to ensure high-speed production and uniform casting film, the air knife on the cooling roller forms a thin layer of air between the film and the surface of the cooling roller, and the vortex air pump cools the film evenly; Simultaneously used for vacuum feeding, drying, dehumidification, and central feeding system of injection molding machines.
3. Computer monitors, LCD monitors, printed circuit boards, and other products can be used in printed circuit board equipment such as vortex air pump cleaning, water cutting, and drying.
4. In wire and cable equipment, it can remove moisture, oil, dry, and suppress static electricity, such as removing water from precision copper pipes for air conditioning.
5. Effective control of coating thickness and ensuring uniform thickness in painting equipment; Can dry, remove moisture, dry at high temperatures over a large area, and control coating thickness; After electroplating, metal surface treatment such as cutting, drying, and degreasing.
6. High pressure vortex fan is used for pneumatic conveying of cans; The use of cutting water, drying, and other food and beverage filling equipment before coding or labeling beverage bottles, cans, and various packaged foods.
7. Printing equipment: screen printing machinery; UV polishing machine, instant drying of ink within 1-5 seconds after printing.
8. Air treatment equipment that can be used for the collection, purification, and recycling of toxic and harmful gases; Gas detection equipment for atmospheric environment.
9. Specially suitable for cleaning equipment such as ultrasonic cleaning machines, PCB board cleaning and drying machines in the electronics industry, tunnel type car cleaning machines (car washing machines), commercial dishwashers, glass cleaning machines, etc.
10. High pressure vortex fans can be used for surface aeration, oxygenation, oxygenation grids, and oxygenation systems in fish farming.

RB-71D-3 high-pressure fanOperation and maintenance:
1. After installation, the air pump should be manually rotated before starting to check for any abnormal collisions or friction, whether the rotation direction of the motor is correct, and whether the inlet and outlet valves are in a low flow state.
2. When the air pump is running, attention should be paid to whether there are any abnormal sounds, oil leaks, abnormal vibrations, high bearing temperatures, excessive motor currents, loose feet, or other abnormal phenomena inside the fan and motor, and they should be eliminated in a timely manner.
3. The bearing grease of the air pump should be replaced after 5000 hours of use.
4. Maintenance: When inspecting the casing, first loosen the screws on the horizontal split surface, open the upper half of the casing and the upper covers of the bearing boxes on both sides, and remove the rotor to repair the rotor or casing. During maintenance, special attention should be paid to whether the impeller blades are broken, whether there are cracks, and whether the main shaft is bent. Before installing and dismantling the machine casing, it is necessary to be careful to avoid damaging the rotor due to the swinging of the upper half of the casing during the installation and dismantling process.
During the shutdown period of the air pump, the inlet and outlet of the fan should be covered properly to prevent debris from falling into the fan chamber and causing accidents.
6. The air pump needs to be inspected every six months to remove dust and oil stains from the fan flow channel.
